It can’t be emphasized enough that the application of a good layer of Mulch, Sugar cane Mulch, Hoop Pine Mulch, Garden Mulch, and Compost on your garden is just as critical as choosing a good garden soil. But first…What is a mulch? Basically a mulch is any form of organic matter that can be used as a barrier between the atmosphere and the soil. This can include, Hoop Pine Mulch, Pine Bark Mulch, Forest Mulch, Sugar Cane Mulch or even your own garden’s leaf litter can be used as a Garden Mulch. In fact when you are next walking in a rain forest, just look down and you will see mother nature at work, mulching her own “garden!”  as the paths are generally covered in decaying organic matter.

All our mulches are held in huge storage bays at our clean depot in Darra where you can see all the mulch you could ever want in the “flesh”. We are often asked, What is the best Mulch? And of course, there is no one perfect mulch for every garden bed and every application. So how do you choose your mulch if there is not one best option? Well, we recommend visiting us here at Darra where you will get a chance to get up close and personal with all of our products. Pick the mulch up, smell it and choose what would look best in your garden!

You can pick all of our bark, pine bark and mulch up from the yard by the shovel, bag full or trailer load. If you need more we can easily and efficiently arrange a delivery to your home or project at a time that suits you. We even deliver on time!

A Short Guide for Mulching your Garden

Mulch Basics

So why is a mulch so important?

And what will it do to help my garden thrive? Here’s 4 Points worth noting…

  1. MOISTURE CONTROL– This is by far the most important reason for using a mulch. Without a good layer of mulch (100mm or 4”), the sun and wind will cause the top 100mm of garden soil to dry out very quickly putting your plants under extreme stress in a very short space of time. By adding mulch, the rate of evaporation is slowed dramatically and with water restrictions, any saving of water usage can only be beneficial not only to the environment but to our hip pockets too. Often we get complaints that plants are not growing well only to find when we visit that the garden has no mulch resulting in the garden soil drying out and even crusting preventing water penetration.
  2. WEED PREVENTION – Having a physical barrier on top of the garden soil will inhibit weeds. Once a seed germinates and reaches the garden soil surface it needs sunlight to photosynthesize (produce food for growth). If a mulch is in place, just its physical presence will prevent most, if not all, potential weed problems thus allowing your plants to thrive without competition. NB. Don’t use plastic under mulch, it prevents the passage of water and gases into the top soil and therefore this can hinder plant growth. We suggest you use “Weed Stop”.
  3. TEMPERATURE MODERATION– This is another benefit of having this physical barrier. In our Queensland climate, top soil will absorb a considerable amount of heat which in an un-mulched garden causes damage to sensitive plant roots near the garden soil surface. Also in those areas that have mild frosts, the mulch will again moderate the temperature making your garden soil a more “enjoyable” environment for your plants to grow!
  4. REPLACING ORGANIC MATTER – As the mulch decays, it helps maintain its open free draining structure. This can be seen if you walk through any rainforest or bushland where the ground underfoot is covered in decaying organic matter or natures mulch… nature’s way of composting or making a mulch.

Here’s How Mulch Works in Your Garden…

This is a very common question and is a valid one considering we at Centenary Landscaping Supplies have over 17 plus to choose from! But when its all said and done, it is true to say that in general, mulch will all do the same job with regards to moisture, weed and temperature control.  In most cases, the buying decision for a mulch can be based on colour, texture and mulch prices to fit your budget.

There are, however, a number of questions that can be asked to narrow the mulch field and help you choose the best mulch for you: And we are here to help you answer those questions…just call 3373 4999 now.

  • Are you matching any other part of the garden with existing mulch?
  • Have you seen a mulch you like at the neighbors?
  • Do you generally like coarse or fine materials as mulch?
  • Is this a show garden, or down the back?
  • Am I just tidying the gardens up to prepare for the house to be sold?
  • Is it a vegetable or herb garden?

What Volume of Mulch Do I Need?

This is a very common but vital question when looking at any gardening project. What you need to do is work out the area of the garden to be covered and simply divide by 10 which gives you the volume needed in cubic metres if the mulch layer is going to be the recommended 100mm (4inches).

Another way of thinking about it is: One cubic metre of mulch will cover ten square metres at a depth of 100mm (4 inches). Always remember, that you can call us at the office and get us to check over your figures if you just wanted to make sure …. Sometimes two heads are better than one!

Over ordering is a waste as you’ll be giving the excess to your grateful neighbour. Ordering to little can also be a waste as the mulch will not do the job you expect and you’ll be needing to order more mulch sooner than later.

What about Plastic or Weedmat under the Mulch?

One of the main reasons for actually mulching the garden is to minimize the amount of weeds that come through and there is no doubt that putting a layer of material under the mulch will help prevent weeds coming through.

That said, plastic should definitely NOT be used as a weed control mechanism. The reason for that is that while it will stop a lot of weeds, it will not let water drain through the mulch and into the garden soil where it needs to be in order to be accessed by the plants. It also could trap small pools of water under the mulch that could become stagnant and smell, or even breed mosquitoes.

If you are reading this and have already used plastic…. The solution is to wander around the garden with a garden fork, punching holes through the plastic layer so that water can drain away. Weedmat or Mulch Mat are thin woven fabrics that will let the garden breathe, let the water drain through while preventing most weeds from coming through. Also it’s a nightmare renovating a garden that has plastic under the mulch and growth. Pulling it out is a real pain and just hard work.
